Sub-technique of: T1564
Adversaries may use hidden windows to conceal malicious activity from the plain sight of users. In some cases, windows that would typically be displayed when an application carries out an operation can be hidden. This may be utilized by system administrators to avoid disrupting user work environments when carrying out administrative tasks.
Adversaries may abuse these functionalities to hide otherwise visible windows from users so as not to alert the user to adversary activity on the system.
On macOS, the configurations for how applications run are listed in property list (plist) files. One of the tags in these files can be apple.awt.UIElement, which allows for Java applications to prevent the application's icon from appearing in the Dock. A common use for this is when applications run in the system tray, but don't also want to show up in the Dock.
Similarly, on Windows there are a variety of features in scripting languages, such as PowerShell, Jscript, and Visual Basic to make windows hidden. One example of this is powershell.exe -WindowStyle Hidden.
The Windows Registry can also be edited to hide application windows from the current user. For example, by setting the WindowPosition subkey in the HKEY_CURRENT_USER\Console\%SystemRoot%_System32_WindowsPowerShell_v1.0_PowerShell.exe Registry key to a maximum value, PowerShell windows will open off screen and be hidden.
In addition, Windows supports the CreateDesktop() API that can create a hidden desktop window with its own corresponding explorer.exe process. All applications running on the hidden desktop window, such as a hidden VNC (hVNC) session, will be invisible to other desktops windows.
Adversaries may also leverage cmd.exe as a parent process, and then utilize a LOLBin, such as DeviceCredentialDeployment.exe, to hide windows.
Platforms: Linux, macOS, Windows
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
Launch PowerShell with the "-WindowStyle Hidden" argument to conceal PowerShell windows by setting the WindowStyle parameter to hidden. Upon execution a hidden PowerShell window will launch calc.exe
Supported Platforms: windows
Start-Process #{powershell_command}
The following Atomic Red Team test leverages the Chrome headless browser to access a mockbin site. Create your own Mockbin.org site and replace the BIN in the inputs. The default Mockbin ID forwards to google.com and you may view the details here https://mockbin.org/bin/f6b9a876-a826-4ac0-83b8-639d6ad516ec/view. Reference: https://cert.gov.ua/article/5702579
Supported Platforms: windows
start "" #{browser} --headless --disable-gpu https://mockbin.org/bin/#{bin_id}
Launch conhost.exe in "headless" mode, it means that no visible window will pop up on the victim's machine. This could be a sign of "conhost" usage as a LOLBIN or potential process injection activity. conhost.exe can be used as proxy the execution of arbitrary commands
Supported Platforms: windows Elevation Required: Yes
conhost.exe --headless calc.exe
If Atomic Red Team tests are not applicable, manually verify the technique by:
Identify Attack Surface: Determine if the target environment is susceptible to Hidden Window by examining the target platforms (Linux, macOS, Windows).
Assess Existing Defenses: Review whether mitigations for T1564.003 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
Limit or restrict program execution using anti-virus software. On MacOS, allowlist programs that are allowed to have the plist tag. All other programs should be considered suspicious.
Restrict the installation of software that may be abused to create hidden desktops, such as hVNC, to user groups that require it.
